Our data does not show a city-level STR ordinance in Ontario, CA, but that does not mean STRs are unregulated here.
California has no state preemption of short-term rentals, meaning cities retain broad authority to ban STRs, cap permits, require licenses, or restrict how often you can rent; some California cities like Los Angeles, Santa Monica, and San Francisco have enacted aggressive restrictions including primary residence requirements and night caps.
There is no state-level STR lodging tax (0%), but local Transient Occupancy Tax (TOT) will apply.
Contact the City of Ontario directly to confirm any local permit, zoning, or TOT obligations before listing.
